• Question 474:

  What is the default value for the errdisable recovery interval in a Cisco switch?

  A. 30 seconds
  B. 100 seconds
  C. 300 seconds
  D. 600 seconds
  C. 300 seconds

  ---

  After you fix the root problem, the ports are still disabled if you have not configured errdisable recovery on the switch. In this case, you must reenable the ports manually. Issue the shutdown command and then the no shutdown interface mode command on the associated interface in order to manually reenable the ports. The errdisable recovery command allows you to choose the type of errors that automatically reenable the ports after a specified amount of time. The show errdisable recovery command shows the default error-disable recovery state for all the possible conditions. cat6knative#show errdisable recovery ErrDisable Reason Timer Status udld Disabled bpduguard Disabled security-violatio Disabled channel-misconfig Disabled pagp-flap Disabled dtp-flap Disabled link-flap Disabled l2ptguard Disabled psecure-violation Disabled gbic-invalid Disabled dhcp-rate-limit Disabled mac-limit Disabled unicast-flood Disabled arp-inspection Disabled Timer interval: 300 seconds Interfaces that will be enabled at the next timeout: Note: The default timeout interval is 300 seconds and, by default, the timeout feature is disabled.

  GLBP Active Virtual Gateway Members of a GLBP group elect one gateway to be the active virtual gateway (AVG) for that group. Other group members provide backup for the AVG in the event that the AVG becomes unavailable. The AVG assigns a virtual MAC address to each member of the GLBP group. Each gateway assumes responsibility for forwarding packets sent to the virtual MAC address assigned to it by the AVG. These gateways are known as active virtual forwarders (AVFs) for their virtual MAC address. The AVG is responsible for answering Address Resolution Protocol (ARP) requests for the virtual IP address. Load sharing is achieved by the AVG replying to the ARP requests with different virtual MAC addresses. Reference: http://www.cisco.com/en/US/docs/ios/12_2t/12_2t15/feature/ guide/ft_glbp.html

  E. The port immediately begins to drop all traffic.
  F. The port enters the shutdown state.
  A. The port enters the err-disabled state.
  B. The Security Violation counter is incremented and the port sends an SNMP trap.
